2. Site Planning

Site planning for the StackMasterTR Stack requires consideration both of site conditions and of token ring standards.

2.1 Site Considerations

The site for the StackMasterTR Token Ring Stack must provide the following:

AC power outlet for each StackMasterTR Unit

Adequate ventilation

Standard environmental conditions

Isolation from electrical noise, including radio transmitters and broadbank amplifiers, motors, high power electrical lines, or fluorescent light fixtures

Additionally:

The token ring cables should not run in the same conduit with power line cables.

Phone lines should be separated from data cables.

Flat or “silver satin” wires should not be used.
